Grid Computing The basic principle behind grid computing is saving cost by using resources efficiently. Grid computing provides the necessary scalability and redundancy. This concept is similar to RAID (Redundant Array of Independent (Inexpensive) Disks). RAID is used to store redundant data to improve performance. Grid computing goes a step further by allowing dynamic addition or removal of devices according to demand requirements. Grid computing helps adjust to business demands without additional costs. It guarantees reliability, scalability and availability of resources. “Grid computing enables groups of networked computers to be pooled and provisioned on demand to meet the changing needs of business. Instead of dedicated servers and storage for each application, grid computing enables multiple applications to share computing infrastructure, resulting in much greater flexibility, cost, power efficiency, performance, scalability and availability, all at the same time.” (Oracle.com) Scalability

It is very hard for a database to respond to unexpected high business demand in a relatively short period of time. There is also a limitation to the database’s capacity to grow. Grid computing becomes an ideal solution in this situation. Oracle 10G has modules to handle unexpected or unusual increase in database demand. Reliability and Availability

Today businesses rely more and more on technology. Online business web sites must be able to respond to a sudden increase in activities. They need more resources to accommodate the surge in demand. With Grid computing, resources are made available whenever demand peaks. Proper resource utilization creates a more reliable environment for databases and applications. Performance

INTRODUCTION:
In the last few years there has been a rapid exponential increase in computer processing power, data storage and communication.But still there are many complex and computation intensive problems, which cannot be solved by supercomputers.These
problems can only be met with a vast variety of heterogeneous resources. The increased use and popularity of the Internet and the availability of high-speed networks have gradually changed the way we do computing. These technologies have enabled the
cooperative use of a wide variety of geographically distributed resources as a single more powerful computer. This new method of pooling resources for solving large-scale problems is called as gridcomputing. This paper describes the concepts underlying gridcomputing.

HISTORY:
The term gridcomputing originated in the early 1990s as a metaphor for making computer power as easy to access as an electric power grid. The power grid metaphor for accessible computing quickly became canonical when Ian Foster and Carl Kesselman published their seminal work, "The Grid: Blueprint for a new computing infrastructure" (2004).

Abstract – In gridcomputing, the total work load is distributed among many computers which are linked together through some kind of local or global network topology. There is no restriction of work it could be of any type like mathematical calculations or processor performing different tasks. Also gridcomputing do not bounds the computers linked together and they could be used also as in normal conditions they are being used A supercomputer could be created by linking different computers through gridcomputing. This research paper presents a comprehensive survey to gridcomputing technology and clarifies its different aspects in the domain of high speed huge data volume based computing. The research paper also investigates emerging trends in the modern gridcomputing technology. Gridcomputing is one the stat of the art technologies being used for high speed...

Clusters And Grid
A computer cluster is a group of linked computers, working together closely so that in many respects they form a single computer. The components of a cluster are commonly, but not always, connected to each other through fast local area networks. Clusters are usually deployed to improve performance and/or availability over that of a single computer, while typically being much more cost-effective than single computers of comparable speed or availability.Grid computing is something similar to cluster computing, it makes use of several computers connected is some way, to solve a large problem. The big difference however, is that a cluster is homogenous while grids are heterogeneous. The computers that are part of a grid can run different operating systems and have different hardware whereas the cluster computers all have the same hardware and OS. A grid can make use of spare computing power on a desktop computer while the machines in a cluster are dedicated to work as a single unit and nothing else. Grid are inherently distributed by its nature over a LAN, metropolitan or WAN. On the other hand, the computers in the cluster are normally contained in a single location or complex.Also in Clusters, all nodes are set to perform a same task, controlled and scheduled by some same...

...Grid Designing
Abstract: In an increasing number of scientific disciplines, large data
collections are emerging as important community resources. Gridcomputing has emerged as an important new field, distinguished from
conventional distributed computing by its focus on large-scale resource
sharing, innovative applications, and, in some cases, high performance
orientation. The foundation of a grid solution design is typically built
upon an existing infrastructure investment. However, a grid solution
does not come to fruition by simply installing software to allocate
resources on demand. The grid solutions are adaptable to meet the needs
of various business problems only because differing types of grids are
designed to meet specific usage requirements and constraints. Different
topologies are designed to meet varying geographical constraints and
network connectivity requirements. The success of a grid solution is
heavily dependant on the amount of thought the IT architect puts into the
solution design. Harnessing these new technologies effectively will
transform scientific disciplines ranging from high-energy physics to the
life sciences. . In this paper, we discuss designing of grid along with
underlying topologies and models that allow for gridcomputing to work.
